RAD9A

RAD9 homolog A (S. pombe)

On chromosome: 11q13.1-q13.2
Known also as: RAD9;


NCBI Gene ID: 5883
NCBI Ensembl Id: ENSG00000172613
MIM Id: (from NCBI OMIM database) 603761
Species: Homo sapiens

This gene product is highly similar to Schizosaccharomyces pombe rad9, a cell cycle checkpoint protein required for cell cycle arrest and DNA damage repair in response to DNA damage. This protein is found to possess 3' to 5' exonuclease activity, which may contribute to its role in sensing and repairing DNA damage. It forms a checkpoint protein complex with RAD1 and HUS1. This complex is recruited by checkpoint protein RAD17 to the sites of DNA damage, which is thought to be important for triggering the checkpoint-signaling cascade. Use of alternative polyA sites has been noted for this gene. [provided by RefSeq]
